I found the issue being when i clip one end of the circuit to the router whilst plugged in(but not on obviously), it causes the issue, so to solve, i just don't have any power to the router at all until I am zeroed.

One question can you explain the differences between reference tool and measure tool?

some people mentioned that Estlcam takes several minutes to load large CNC files.I've found the issue and uploaded an update: www.estlcam.com (Version 8.212)It should now be able to load even very large files within a few seconds.

I have a wired Problem with Estlcam USB controller. The patterns Estlcam carve to small. When I want to carve a 50mmx50mm sqaure, Estlcam carves a square with roughly 40x40mm.The generatet G-Code from Estlcam ist fine. I can send it UGS and my X-Carve works fine with a 50x50mm sqaure.My Setup is: - Arduino GRBL PWMAll axis same values:- Steps per revolution: 1600- Travel per revoluztion: 40mm- max feed reate: 5000mm/min

I can't remember my values, but the easy way to set them is to say start at 8000, then use the controller to move the axis at the fastest. Chances are it will stall. Lower the value and try again. I would drop down by 1000, until it works fine, then up by 500. I think I was able to do about 5000 for X and Y and 750 for Z

I am still not sure about the maximum feed rates. Any suggestions on that?

Finding reliable feed and acceleration settings is explained here from 2:43 to 4:33:

Basically you start at a low feedrate, apply the change and see what happens if you move the axis at full speed by clicking the corresponding arrow in the controller window at its maximum speed position.

If it works well increase the value and try again...

If the axis stalls go back to the last working value and further decrease it by a 20-30% safety margin. This is important otherwise your machine will not be reliable because any minor issue may cause step losses.

If you want even better settings make a series of tests also with different acceleration distances:

Change the acceleration value, repeat the above test and note the final feed rate settings.

If you plot it as a X / Y diagram you'll also notice an area where further increasing acceleration distance won't improve speed anymore.

Finally you have to find a compromise between feed and acceleration - I usually prefer a setting where the machine achieves about 80% of its maximum speed to avoid compromising acceleration too much.

For things like picture engravings where you have thousands of short moves with constant accelerations I optimize for extreme acceleration settings as the machine won't reach maximum feeds at the short distances anyway. This can cut machining times down to a fraction of the time you'd need with a more traditional setting.

@ChristianKnull this new mapping feature has me sold on your software. My only hesitation is this: I've upgraded to the Xcontroller. Without the Arduino/Gshield configuration that was originally shipped, will Estlcam still work with the new hardware?

I don't know too much about the X-Controller - but as it runs GRBL it should be compatible unless there are some fancy modifications to the hardware or bootloader.If someone gives it a try please let me know.
